De-risking decarbonization

Helping climate-tech startups and investors avoid expensive mistakes in cost estimation

The Problem

Many climate-tech startups fail at the Series B or C stage because scaling costs were never properly understood.

At some point, a third-party (due-diligence expert, EPC, consultant) is brought in to conduct a cost estimate (AACE class 5 or equivalent). When the results come back, the large-scale equipment/installation/plant will often cost significantly more than the startup originally anticipated — enough to derail the entire business.

Common failure modes:

  • Core tech has hidden cost flaws that emerge only at scale

  • Un-optimized process and balance-of-plant design

  • Loose, top-down “cost-factored” estimation methodology with poor grounding in the actual design

Each of these can result in missed targets, blown budgets, and ultimately — bankruptcy.

A Better Way

What if these issues were caught earlier, at the seed stage, or series A?

By doing rigorous, bottom-up cost estimation early — even when the hardware is only at the lab scale — you gain critical visibility into the economic feasibility of your design.

This lets you:

  • Identify and pivot from costly core tech flaws

  • Optimize your design when changes are still cheap

  • Keep later-stage EPCs and cost estimators honest

  • Build credible financial models to raise capital more effectively

Who we serve:

Start-ups

Avoid surprises at Series B or C by understanding your scale-up costs now. We help you build a grounded cost estimation plan — starting from your earliest prototypes.
